CookieSieve

CookieSieve is a browser-based privacy assistant that automatically handles cookie banners and consent pop-ups with strict, user-defined rules. Instead of just clicking “Reject all,” it detects dark patterns (e.g., pre-ticked boxes, confusing toggles, misleading colors) and applies a consistent privacy-first choice across sites. It maintains a local audit log showing what was accepted/blocked and flags sites that ignore your choices or re-prompt excessively. The product is realistic because it focuses on a narrow, frequent annoyance that users feel daily, and it doesn’t require impossible “total privacy” promises. The hard part is keeping up with constantly changing banner frameworks and site-specific implementations, so the MVP should target the most common CMPs first (OneTrust, TrustArc, Quantcast) and expand coverage over time. It’s a combination traditional + AI app: rules and selectors plus ML-based banner detection.
